Has WD bit off own hand?

Recommended Posts

With the release of the WD RE3, it seems that it's not only superior in performance but much for cost effective?

Test results by BlackDragon24 at AMDMB :

Western Digital 2 x 250 GB RE3 RAID 0 ICH9R 128k stripe.

The RE3 drives are remarkable, especially when you but them up against a solution that costs 4 times as much like the velociraptors:

2 x 300 GB Velociraptors RAID 0 32K Stripe ICH9R

I suppose the Velociraptors are extinct.

STR doesnt matter nowadays. Nobody is buing velocirators because of it, at least.

what would perform better (more concerned with access time than sustained transfer speed)

2x640gb WD Black or 2x320gb WD RE3 ?

All else being equal, if you put the same amount of data on two drives with the same areal density, the drive with 2 platters will have better access time than the drive with 1 platter because the data will occupy half the width of the platters* on the 2 platter drive.

If you are concerned primarily with access time (which is, after all, the primary predictor of storage performance), a single drive will perform better than 2 in RAID 0. RAID 0 slightly increases access time because you can incur rotational latency waiting for the stripe to come around.

* "half the width" metaphorically speaking, since we are talking about circular tracks
